Pupupuland in Minecraft WIP

I'm not sure if this really counts as 'fan art', but I'm not making a board all for Minecraft (and it's my forum, so there. =P), so this is the closest I can get. I've started making Pupupuland in Minecraft. It's going to be difficult, especially without World Edit, but I'm doing it anyway. I'm using Tekkit so I can use mods for more block choices. I loaded it as a Superflat world, meaning there are no hills and mountains at all. As we all know, Pupupuland is filled with mountains, cliffs, hills, etc, so I'm going to have to make them manualy. I tried installing World Edit, and it won't work for whatever reason.

Anyway, this is all I have so far:

As you can see, I only have the tree, the Police Station, and the building next to it. The star on the Police Station turned out really ugly, I'll likely remake it later. The building right next to it doesn't look wide enough. I'm using these to help:

Update #1: This project IS hell. I was right. Right now, I'm trying to figure out where the buildings will be, and placing signs as reminders.

Posting pictures will be difficult, since I'm using Tekkit. When I take a screenshot with it, I can't find where it's saving them. So I'm going to have to use the 'prt sc' button instead, then pasting it into MSpaint, which is what I did in the OP. I'll post pictures of this update later. What I did is, like I mentioned before, placing signs to locate locations of buildings. I placed signs for the toy store, gas station, and resteraunt. I also placed signs where I'll have Whispy Woods and the castle, both of which will be torcher to build, especially the latter, with how large it is and the fact that I'll have to manually build a cliff.

I also added a room to the police station, which is the actual 'house' part. Then I started building this thing:
